    Large-grain quasicrystals and approximant crystals are desirable for the physical properties and surface properties study. In this letter, we present a study on the growth of large-grain icosahedral quasicrystals and 2/1 and 1/1 approximant crystals of Ag-In-Yb alloy using a facile self-flux method in indium-rich melt-solution. The as-grown samples show facets along 5-, 3- and 2-fold planes in the quasicrystal sample, whereas the 1/1 approximant crystal exhibits facets along {1 0 0} and {1 1 0} planes and the 2/1 approximant crystal along the {1 1 1} planes. The facets are considered to be thermodynamically favorite planes in the above crystals and they offer valuable information for understanding the surface stability in icosahedral quasicrystals.
